– Why do electric devices with batteries (phones, electric cars, …) can only be charged by one charger at a time?

461 views

Hi, with all the boom of “fast charging” I’ve been wondering why can’t we have phones or electric cars with twice or more the charging ports. I understand that is inconvenient to plug two chargers instead of one but wouldn’t that increase the charging rate, solving one of the problems with electric cars (refueling gas is way faster). As this is not the case there should be a good reason why it is not feasible, what is it ?

(I did not find anything close to convincing in google).

The limitations are rarely the charging connector itself. USB power delivery supports 100 watts over the USB-C connector if the appropriate hardware was installed into the device being charged (and an appropriately electrically marked cable), although for a phone such a charging rate would probably be very unsafe for the battery being charged.

For electric cars you would probably also have to seriously consider how that much electricity would be delivered to the charging dock.
